Why Climate Defenders Shouldn't Fear Trump

Climate scientists were startled by U.S. President-elect Donald Trump's choice for head the Environmental Protection Agency. Scott Pruitt is Oklahoma's Attorney General, a self-avowed climate change denier and a strong critic of the actions of the EPA under President Barack Obama. Bloomberg TV Canada's Rudyard Griffiths speaks to Bob Perciasepe, president of the Center for Climate and Energy Solutions and former deputy administrator of the EPA. Perciasepe says it would be very difficult for Trump to reverse some of the enacted climate policies. (Source: Bloomberg)
